Seem like something’s missing from the 6.2 feature list? You’re right… We wanted to get 6.2 wrapped up and in your hands before the new year while we take a little longer to incorporate your testing feedback on the scanner changes.

Be on the lookout in the coming days for a 6.3 alpha announcement that will include the scanning features."
